Within the dairy industry the appearance of milk and withdrawal time due to antibiotic residuals in the milk are used to determine recovery status after cases of treated mastitis. However, both milk production and dairy cow behavior, including their inclination to being milked, have been shown to be affected after the normalization of milk appearance, indicating that animals may not have fully recovered.
The study took place on two Danish farms on 795 cows milked by automatic milking systems and a total of 174 treated mastitis cases were compared with non-treated control cows.
